摘　　要：以２．９６×１０１４Ｂｑ６０Ｃｏ为辐照源，对直接耐晒大红４ＢＳ等五种偶氮染料水溶液进行γ－辐照。结果表明，它们能有效降解和脱色，剂量为１２ＫＧｙ时，其降解度为３０～８０％，脱色度均超过８０％，ＣＯＤ去除率为５０％～６０％。另外，还做了吸收剂量、乙醇和Ｈ２Ｏ２的影响试验。The degradation of 5 azodyes solutions has been studied under 2.96×10 14 Bq 60 Co radiation source. Results show they can be degraded and decolorized effectively, with the degradation degrees 30%￣80%, decoloration degrees above 80% and COD decrease up to 50%￣60% under 12KGy dosage. The efficiencies of their degradation and decoloration are raised as the dosage increases. Hydrogen superoxide can promote their degradation, however, ethanol can prevent the degradation. Our experiment will provide a potential way for treating high concentration and refractory wastewater.
